Question

Evaluate log10

Answer 1

The logarithm of a number to a given base is the index of the power to which the base must be raised to give the number.

Examples
log10 (1000) = 3---------10³ = 1000
log2 (16) = 4--------------2^4 = 16
log3 243 = 5--------------3^5 = 243

Thus log10 (10,000) = 4 <--------10^4 = 10,000

Answer 2

solve for x
10^x = 10

assumed log 10 will be x
